Pressure variations resulting from the oscillatory flow patterns found in positive-displacement machinery, especially reciprocating compressors, are referred to as “pulsations.” Found in both liquid- and gas-handling systems, pulsations are a common phenomenon in the chemical processing industries (CPI). Operational problems associated with pulsations include resonance conditions, high...

Polymers like polyethylene, polypropylene, polyvinyl chloride and polyester have become ubiquitous in manufacturing. The properties of polymer-based materials that make them so desirable — they are generally cheap to produce and boast high chemical and thermal stability — also make them abundant, disposable and, in many cases, non-degradable. As landfill space decreases, and with some European...

The chemical process industries (CPI) are, by their very nature, global in scope. While chemical process operators share many common aspects (in terms of the use of chemical engineering unit operations), the location of their operation brings about different requirements when it comes to managing gaseous and particulate pollutants, because different countries have different regulations with regard to air...

Compressible gas flow with significant variation in density along pipes is commonplace in the chemical processing industries (CPI). In designing these pipes for compressible flow, it is important to calculate the pressure loss or maximum gas-handling capacity for safety and economic reasons. Due to the complexity of the equations for compressible flow, which often require time-consuming iterations, current...

Would you like to make a quick mental calculation to determine approximate flowrate, velocity, or pipe and duct sizes for many common situations? This article presents two methods for estimating flow characteristics without the aid of charts, tables, calculators or software programs. One method applies to liquid flow in pipes, and the other to air flow in ducts. The techniques are intended to be simple...

Beginning with the early days of automated multivariable control in the 1980s, the trend has always been toward the use of larger matrices and more models. Today’s multivariable controllers commonly comprise dozens of variables and hundreds of models. But the next big advancement in multivariable control may be a shift toward the use of small-matrix, model-less multivariable control practice...

Have you ever heard someone say, “The job is a lot easier if you have the right tools?” Having the right tools is critical to the success of craftsmen, such as carpenters, electricians, plumbers and the like. The same holds true for managing projects. Initiating a project raises many questions (such as: What will we do? How will we do it? Who will do it? How much will it cost? When will we do...

FRI’s membership has been growing steadily since 2006. As a result, I have more bosses every year; at present, 78. I receive input from them in several ways. They attend quarterly meetings. They respond to surveys and votes. They send emails. They call. Primarily, this column describes the projects that are presently of the most interest to the membership. In 2013, 8-ft-dia. two-pass valve trays were...
